  ABSTRACT: Aim: To report a case of longer-lived patent ductus arteriosus with features of pulmonary arterial hypertension up to the age of 65 years in an elderly woman. Introduction: The clinical recognition of patent ductus arteriosus with severe pulmonary hypertension is difficult. Only 60% of adults presented with a continuous murmur in a recent series. Asymptomatic patent ductus arteriosus tolerated for many years and may not require closure. Case Report: A 65 years old female presented with dyspnea had signs of pulmonary arterial hypertension with enlarged pulmonary artery and its branches, atrial fibrillation along with a continuous murmur in the left second intercostal space. Echocardiography revealed a 13 mm size patent ductus arteriosus and a bidirectional with predominant left-to-right shunt. Patient was managed conservatively and symptoms got improved with medical therapy. Conclusion: Treatment of patent ductus arteriosus in the setting of pulmonary hypertension is challenging. Early repair can mitigate the development of pulmonary hypertension and reverse vasculopathy in more advanced disease. Maternal aspirin ingestion should be avoided in pregnancy since it causes constriction of fetal ductus.
